Which miniITX board? GIGABYTE B550I AORUS Pro AX or ASUS ROG Strix B550-I Gaming?

Hi all. I need some help deciding between these two miniITX boards: GIGABYTE B550I AORUS Pro AX and ASUS ROG Strix B550-I Gaming. (the other B550 miniITX boards are out of question).

 

The system will go into a Streacom F1C WS case, so it will be quite cramped and tend to be a bit warmer, mainly because I'd prefer the whole thing to be a bit quieter, which is why I want to undervolt the CPU a bit and run the fan on rather RPMs.

 

The system will mainly be used for home office/surfing and will mostly be in idle-like states. Every now and then old FPS (in 4k) will be gamed. OS will be Linux, so I probably won't be able to use any software that is provided with the board.

 

The most important questions for me:
1. Which network chip is (by now) better/more reliable? Intel I225-V or Realtek RTL8125B-CG? I've already read of unfixed bugs regarding both chips.
2. Do the higher quality VRMs of the Gigabyte board provide lower temperatures?
3. Is CPU undervolting equally good/easy on both boards?
4. Regarding the setting of the fan curve, I guess there is probably no big difference?

 

I'm also looking forward to further hints and suggestions :)

1. Not sure, but never had an issue with an Intel network adapter

2. Depending on the processor used and overclock, both are fine to handle even the largest chips at stock.

3. Yes, but if you have proper cooling, this shouldn't be a consideration.

4. Fan curve? That is a preference thing. Your max temp target on both boards will be 75c however.

 

I have a B450-I Strix. I gotta say it's probably one of my most favorite boards I've had in the last 15-20 years now. (opinion)

1. I wanted to try Intel networking but Realtek never failed me either. Probably because I didnt spend enough on boards or laptops so they only come with cheap networking #kappa

 

2. Not really, Asus runs active cooling for VRM here (small fans below the I/O cover). I cant tell which one will run hotter.

 

3. If you're used to both BIOS designs, yes. Gigabyte's harder to get used to though

 

4. No difference, both are simply dots on a graph.
